OpenTofu The Linux Foundation
winget install --id=OpenTofu.Tofu.Beta -e OpenTofu lets you declaratively manage your cloud infrastructure.
OpenTofu is an open-source tool designed to safely and efficiently build, change, and version cloud infrastructure through Infrastructure as Code (IaC). It enables teams to manage existing and popular service providers, as well as custom in-house solutions, by providing a declarative approach to infrastructure management.
Key Features:
- Infrastructure as Code: Define cloud resources using a high-level configuration syntax, enabling versioning, collaboration, and reuse of infrastructure blueprints.
- Execution Plans: Generate detailed execution plans to preview changes before applying them, ensuring transparency and minimizing surprises during deployment.
- Resource Graph: Visualize dependencies between resources and optimize the creation or modification of non-dependent resources for efficient infrastructure builds.
- Change Automation: Apply complex changesets with minimal human intervention, leveraging the execution plan and resource graph to avoid errors and ensure consistency.
Audience & Benefit: Ideal for DevOps engineers, cloud architects, and development teams who need to manage cloud infrastructure at scale. OpenTofu provides tangible benefits such as improved infrastructure reliability, reduced manual errors, faster deployment cycles, and enhanced collaboration through version-controlled infrastructure definitions.
OpenTofu can be installed via winget on Windows systems.
README
OpenTofu
OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu can manage existing and popular service providers as well as custom in-house solutions.
The key features of OpenTofu are:
-
Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
-
Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.
-
Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
-
Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
